Neutrino Physics and Astrophysics at Colliders
Nonzero neutrino masses guarantee new physics and neutrinos are excellent probes of extreme environments in the Universe. The recent collider neutrino experimental program, including FASER$ν$ and SND@LHC, along with the planned Forward Physics Facility at the High-Luminosity Large Hadron Collider, is opening a new window into neutrino physics and astrophysics. In this article, we review recent achievements and prospects of collider neutrino experiments, including key achievements such as the f…

3C 403: a candidate neutrino-emitting radio galaxy
3C 403 is a well known FRII radio galaxy, whose jets extend up to the kpc scale. In this letter, we present its identification as the second most significant source among the more than 150 inspected using the 15-year neutrino dataset of the ANTARES Collaboration, possibly making it the first radio galaxy with neutrino emission. Following the previous association of blazars with netrinos events, we aimed at studying the jet properties and its possible role in neutrino production. We collected mu…

Auch deswegen sind Krypto-Währungen kein Fortschritt, sondern ein Verlust der Erde von Energie die sie sich Egoisten bezahlt bekommen wollen.

Electric dipole polarizability constraints on neutron skin and symmetry energy
We review the experimental knowledge on the dipole polarizability (DP) of nuclei and its relation to the neutron skin thickness and properties of the neutron-rich matter equation of state (EOS). The discussion focuses on recent experiments using relativistic Coulomb excitation in inelastic proton scattering at extreme forward angles covering a mass range from $^{40}$Ca to $^{208}$Pb. Constraints on the neutron skins and the density dependence of the symmetry energy are derived from systematic c…

Exploring Fermionic Dark Matter Admixed Neutron Stars in the Light of Astrophysical Observations
We studied the properties of dark matter admixed-neutron stars (DMANS), considering fermionic dark matter (DM) that interacts gravitationally with hadronic matter (HM). Using relativistic mean-field equations of state (EoSs) for both components, we solved the two-fluid Tolman Oppenheimer Volkoff (TOV) equations to determine neutron star (NS) properties assuming that DM is confined within the stellar core. For hadronic matter, we employed realistic EoSs derived from low energy nuclear physics ex…

Analytic formulation of Leptogenesis with neutrino oscillation data employing the general parametrization for neutrino mass matrix
The observed neutrino oscillations and baryon asymmetry, unexplained by the Standard Model (SM), can both be accounted for by extending the SM to include Majorana right-handed neutrinos (RHNs). Tiny neutrino masses naturally arise through the Type-I seesaw mechanism, which involves lepton number violation. Meanwhile, the baryon asymmetry can be generated via leptogenesis, where the out-of-equilibrium decay of RHNs produces a lepton asymmetry that is partially converted into a baryon asymmetry t…

Diagnosing electron-neutrino lepton number crossings in core-collapse supernovae: a comparison of methods
Fast neutrino flavor conversion may impact the explosion mechanism and nucleosynthesis in core-collapse supernovae. A necessary condition for fast flavor conversion is the presence of crossings in the angular distribution of the electron-neutrino lepton number (ELN crossing). Because of the computational costs, flavor-dependent angular distributions are not computed by the vast majority of state-of-the-art hydrodynamical simulations; instead, angular distributions are reconstructed employing ap…

An Accretion Flare Interpretation for the UHE Neutrino Event KM3-230213A
We study the origin of the ultra-high-energy (UHE) astrophysical neutrino event KM3-230213A detected by KM3NeT, focusing on MRC 0614-083 which has been pinpointed as the closest blazar to the neutrino localization. A joint interpretation of the optical, infrared, and X-ray light curves suggests that MRC 0614-083 has undergone a super-Eddington accretion flare accompanied by efficient proton acceleration. That flare has initiated a delayed infrared echo within the surrounding dust torus, which s…
